Definitions

  • the binding is primarily designed for crosscountry skiing and includes a plate which is adapted to be secured to the top surface of a ski.
  • a pair of upstanding retaining flanges extend upwardly from a front end of the plate, each of the upstanding flanges including a means to engage and retain an outwardly projecting pin on the sole of the boot.
  • Means are provided on the retaining flanges for releasing the pins from engagement with the engaging and retaining means.
  • a U-shaped bracket is fixed to a rear portion of the plate with the legs of the bracket extending upwardly from the ski to engage the sides of the boots retained by the binding.
  • at least one of the pins is spring loaded and the releasing means comprises a lever pivotably mounted to an upstanding flange, the lever having a camming portion adapted upon actuation to bear against the spring loaded pin to release the pin from engagement with the retaining flange.
  • the pins are fixed within the boots, a slot is provided in the retaining flanges for reception of the pins, and a spring biased latch retains the pins within the slot.
  • This invention relates to a ski boot binding.
  • the invention relates to a cross-country ski boot binding wherein the ski boot has outwardly projecting pins at a front portion thereof which are received and releasably retained by the binding.
  • Cross-country ski boot bindings are a means of securing the boot to the cross-country ski.
  • the heel of the boot is permitted to move upwardly away from the ski whereas the toe of the boot is retained fixed against the ski so that the skier can raise his heel while skiing much the same way that one does while walking.
  • One commonly used ski boot binding provides a pair of upstanding flanges for engagement with the sole of the ski boot.
  • a pair of protuberances on the flanges fit over the sole of the ski boot to retain the sole therebeneath.
  • a cable is secured tightly around the heel of the ski boot to force the boot into engagement with the retaining flanges of the binding.
  • cross-country ski boot binding requires a special boot with a square extended sole at the front portion thereof.
  • the binding comprises a toggle clamp which clamps onto the squared extended portion of the sole.
  • This type of binding offers more heel control than the cable binding but requires a special type of boot which is adapted almost exclusively for crosscountry skiing.
  • a crosscountry ski boot binding wherein the soles of the shoes are provided with outwardly directed pins at a front portion thereof.
  • the pins can be mounted in conventional hiking boots by a simple process, or the boots can be specially constructed with the pins.
  • the boot can be of any shape and can be used as a hiking boot or any other type of boot.
  • the binding comprises a plate which is secured to the upper surface of a ski and a pair of upstanding retaining flanges at a front end of the plate.
  • Each of the retaining flanges includes a means to engage and retain the outwardly projecting pins of the boot.
  • At least one of the retaining flanges mounts a means for releasing the pins from engagement with the retaining flanges.
  • a U-shaped bracket is fixed to a rear portion of the plate with the legs of the U-shaped bracket extending upwardly to abut against the sides of a boot retained by the binding. The U-shaped bracket at the rear portion of the plate does not interfere with the normal operation of the boot and retains the boot in its predetermined orientation to give added heel control during downhill skiing.
  • At least one of the pins in the boot is spring loaded and the retaining end engaging means comprises a lever pivotably mounted on one of the upstanding flanges, the lever having a camming surface adapted to cam said pin out of engagement with the opening in the retaining flange.
  • the retaining and engaging means comprises a slot in the upstanding retaining flanges and a latch, pivotably mounted to the retaining flanges, the latch hooking behind the pins to retain the pins in the slots.
  • the latch is movable to a position for releasing the pins from the slot and means are provided to bias the latch in the retaining position with respect to the pins.
  • FIG. 1 is a plan view of a binding according to the invention
  • FIG. 2 is a side elevational view in section taken along lines 22 of FIG. 1;
  • FIG. 3 is a front elevational view in section along lines 33 of FIG. 1;
  • FIG. 4 is a sectional view through lines 4-4 of FIG.
  • FIG. 5 is an enlarged side elevational view of a release mechanism associated with the first embodiment
  • FIG. 6 is an enlarged partial plan view of the release mechanism illustrated in FIG. 5;
  • FIG. 7 is a partial sectional view along lines 7-7 of FIG. 5;

  • FIGS. 1 7 there is illustrated a ski 12 having a binding 14 secured to the top portion thereof through a plurality of screws 16.
  • the binding 14 has a base portion 18 and upstanding retaining flanges 20 and 22 at a front portion thereof.
  • a raised channel 24 is provided transversely of the binding at a rear portion thereof and retains a U-shaped bracket 26 whose legs extend upwardly from the ski to abut against the sides of the boot (shown in phantom lines in FIG. I) retained by the binding.
  • a gripping hole 28 is provided on the upstanding retaining flange 22 for reception of an outwardly directed pin 53 (FIG. 1) which may extend from the sole of the ski boot 46.
  • the upstanding flange 22 has a base 30 with a gripping hole 32 therein for reception of a spring biased pin 54 (FIG. 7).
  • a release lever 34 is pivotably mounted on the upstanding retaining flange 20 by means of pivot pin 36.
  • the front of the release lever 34 includes a camming portion 38 adapted to bear against and force retraction of the spring mounted pin 54.
  • a tab 40 on the rear portion of the release lever 34 facilitates operation of the release mechanism.
  • a spring 42 is secured at one end to the retaining flange 20 through a pin 44 and at the other end bears against the upper portion of the release level 34 to bias the lever 34 into the inoperative position illustrated in FIG. 5.
  • the shoe 46 has a sole 48 with a bore 50.
  • a housing 52 in the sole 48 slidably retains a spring loaded pin 54 which is biased outwardly by spring 56.
  • the pin 54 desirably is keyed to the housing 52 so that it maintains a particular orientation with respect to the boot and with respect to the binding.
  • the outer surface of the pin 54 is beveled upwardly and outwardly.
  • the upper surface of the camming portion 38 of release lever 34 is beveled corrrespondingly so that as the camming portion 38 bears against the outer end of the spring loaded pin 54, the pin is pushed into the housing 52, thereby releasing the pin from engagement with the hole 32 of the retaining flange 20.
  • the other pin 53 in the sole 48 can also be spring loaded although a spring loaded pin on the other side is unnecessary. Once the pin 54 is released from engagement with the upstanding flange 20, the pin 53 can be easily disengaged.
  • the boot is easily secured to the binding by inserting the pin 53 into hole 28 of the upstanding retaining flange 22.
  • the other side of the boot is then brought down so that the outer end of the pin 54 bears against the top of the base portion 30 above the hole 32 of the retaining flange 20.
  • Downward pressure on the boot will force the pin 54 into the housing 52 so that the pin 54 can move downwardly along the inner surface of base 30 until it reaches hole 32. At this point, the pin moves outwardly under the force of the spring 56 to engage the hole 32.
  • the boot will be tightly retained in the binding with the heel being permitted to move upwardly with respect to the binding.
  • the retaining flanges and 22 are slanted inwardly to retain the front of the boot against forward movement with respect thereto.
  • the upstanding legs of the bracket 26 will restrain lateral movement of a central portion of the boot within the binding. Further, lateral movement of the boot within the binding is restricted by the positioning of the pins 53, 54 of the boot in the holes 28 and 32 of the retaining flanges 22 and 20 respectively.
  • the boot is removed from the binding by simply pressing down on the tab 40 to cam the retractable pin 54 out of engagement with the hole 32 as described more fully above.
  • the ski 12 has a binding 60 secured thereto through a plurality of screws 70 in conventional fashion.
  • the binding has a pair of identical front retaining flanges 62 extending upwardly from a base plate portion 68.
  • Each of the retaining flanges has a retaining slot 64 and a hole 68.
  • a spring member 72 is integrally formed with the base portion 68 and extends upwardly from a front portion thereof.
  • a cradle 74 is formed at a top portion of the spring 72.
  • the base plate portion 68, the retaining flanges 62, and the spring 72 are all stamped from a single piece of material of, for example, a medium carbon steel. The material is of sufficient strength and resiliency such that the spring 72 provides a substantial upward pressure against the retainer 80.
  • a retainer 80 has a bight portion 82 positioned within the cradle 74 of spring 72.
  • the retainer 80 is bent inwardly at 84 around the front portion of the retaining flanges 62 and tits through the holes 66 therein.
  • the retainer 80 extends rearwardly at 86 along the inside edges of the retaining flanges 62 and is bent downwardly at 88 behind the pins 78 in a retaining position illustrated in FIGS. 8 and 9.
  • the inwardly bent portions 84 prevent forward and rearward movement of the retainer with respect to the retaining flanges 62.
  • the boot 46 has a sole 48 with a plate member 76 integrally moldedtherein or otherwise secured within the sole.
  • a pair of pins 78 extend outwardly of the plate portion and outwardly of the sole to engage the retaining slots 64 of the flanges 62.
  • the sole is cut away at to provide a space for rearwardly directed portions 86 of the retainer 80.
  • the retainer 80 is movable between a retaining position illustrated in FIGS. 8 and 9 to a release position wherein the downwardly bent portions 88 move upwardly from behind the pins 78.
  • the spring 72 acting through cradle 74 biases the bight portion 82 of the retainer upwardly with respect to the ski, thereby biasing the downwardly bent portions 88 into the retaining position illustrated in FIGS. 8 and 9.
  • the bight portion 82 is pushed downwardly against the tension in spring 72, whereby the retainer pivots on the holes 66 in the retaining flanges 62 about portions 84 of the retainer 80.
  • the bracket 26 is provided at a rear portion of the base plate 68 with a bracket 26 in the same fashion as illustrated in the first embodiment in the FIGS. 1 and 2.
  • the invention provides a simple means for securing a boot to a ski such that the boot is pivotably secured at a front portion to the ski, yet sufficient retaining means are provided in the connection and ancillary thereto by means of the bracket 26 to assure a positive heel control for the ski.
  • the binding is easily secured to the ski boot and remains so secured during normal use. Yet, the boot is easily removed from the binding when it is desirable to do so.
  • said boot having a sole with a pair of elongated pins mounted at a front portion thereof and projecting outwardly, at least one of the pins being retractably spring loaded in the sole;
  • the binding including a plate secured to the ski, the
  • each of the flanges including an opening to receive and retain the outwardly projecting pins on the sole of the boot;
  • said releasing means including a cam lever with a cam surface positioned to contact the outer end of the spring loaded pin, the cam surface being shaped to retract the spring loaded pin upon movement of the cam lever with respect to the plate.
  • said binding including a plate secured to said ski and a pair of upstanding flanges at a front portion of said plate, said flanges being spaced and sized to snugly receive the front portion of said sole therebetween, each of said flanges including a slot opening rearwardly of the flanges and sized to receive the elongated pins therein;
